Method Detail

• _invoke

  public OutputStream _invoke(String $method,
                     InputStream in,
                     ResponseHandler $rh)

  Description copied from interface: InvokeHandler
  Invoked by the ORB to dispatch a request to the servant. ORB passes the method name, an InputStream containing the marshalled arguments, and a ResponseHandler which the servant uses to construct a proper reply. Only CORBA SystemException may be thrown by this method. The method must return an OutputStream created by the ResponseHandler which contains the marshalled reply. A servant must not retain a reference to the ResponseHandler beyond the lifetime of a method invocation. Servant behaviour is defined as follows:

  1. Determine correct method, and unmarshal parameters from InputStream.

  2. Invoke method implementation.

  3. If no user exception, create a normal reply using ResponseHandler.

  4. If user exception occurred, create exception reply using ResponseHandler.

  5. Marshal reply into OutputStream returned by ResponseHandler.

  6. Return OutputStream to ORB.

  Specified by:

  _invoke in interface InvokeHandler

  Parameters:

  $method - The method name.

  in - The InputStream containing the marshalled arguments.

  $rh - The ResponseHandler which the servant uses to construct a proper reply

  Returns:

  The OutputStream created by the ResponseHandler which contains the marshalled reply
